oead fails to build (CMake <3.5 compatibility error)

[ioistired]

Hello,
When running python setup.py bdist_wheel on Arch Linux, I get the following output:

running build_ext
-- The CXX compiler identification is GNU 15.1.1
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done
-- Check for working CXX compiler: /usr/bin/c++ - skipped

CMake Error at /home/user/code/vcs/git/com/github/@/zeldamods/oead/lib/pybind11/CMakeLists.txt:8 (cmake_minimum_required):
  Compatibility with CMake < 3.5 has been removed from CMake.

  Update the VERSION argument <min> value.  Or, use the <min>...<max> syntax
  to tell CMake that the project requires at least <min> but has been updated
  to work with policies introduced by <max> or earlier.

  Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway.

Exact same problem on Mac.

[EvelynMakesThings]

Same problem, also on Arch.

After some testing it seems to be an issue with the CMakeLists not working with cmake 4? Because after downgrading to cmake 3 on my Mac everything seemed to work just fine.

This is an issue with oead not specifying the CMake version. As a temporary workaround, you can run export CMAKE_POLICY_VERSION_MINIMUM=3.5 before building. I was also getting an error with an unsupported clang option, which can be suppressed with

export CC="clang -Wno-unused-command-line-argument"
export CXX="clang++ -Wno-unused-command-line-argument"

Same issue on Win10, where do you run the export commands?

You can run it in the command line before building. Though on Windows I believe the command is set, not export
